Alexander Laboratory Extraction Arms

The laboratory extraction arm is comprised of thin-wall anodized aluminum tubes with polypropylene swivel joints. A frequent option selection is all polypropylene construction with stainless steel airstream components for highly corrosive airstreams. Additionally, these arms may be constructed of conductive polypropylene material for spark resistance and ATEX-rated explosive applications. Arm tube diameters range from two to four inches, and arm lengths range from two feet up to eight and a half feet. Arms can be paired with a wall or ceiling bracket, several optional hoods, or a suction nozzle. Alexander, Arkansas Laboratory bench mount arms are an option and are available in three and four-inch diameter tubes up to six feet in length.

  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Market-leading low-pressure drop
  • Various hood options for more efficient source capture include dome hoods, square hoods, flat screen hoods, metal hoods, and suction nozzles.
  • Wall brackets, ceiling brackets, and table mount brackets are available.
  • Arm diameters include 2", 3", and 4", and arm lengths include 25", 30", 39", 45",51", 53", 59", 65", 75", 79", 83", and 104".
  • Polypropylene (P.P.), ESD (spark forming applications), and ATEX (combustible applications) options are available.

Alexander ATEX Rated Fume Extraction Arms

Explosion-rated extraction arms are available for the handling of explosive gases and dust. (The combustible materials need to be identified upfront to determine the arm selection and hose material, if there is particulate, is corrosive.) These extraction arms meet the requirements of the ATEX Directive 2014/34/E.U. Category 2 for gases and dust for Zones 1 and 21 (areas where an explosive atmosphere is likely to occur during regular operation). ATEX-rated fume arm tube diameters vary from four to eight inches, and arm lengths are optional from five feet up to twenty-three feet.

  • Flexible PE hose, fully grounded.
  • Arm diameters include 4", 5", 6", and 8", and arm lengths include 5', 7', 10', 13', 16', and 23'.
  • Models having black chemical resistance P.E. hose
  • They are manufactured following ATEX directive 2014/34/E.U. Category 2 for gases and dust.
  • Model having a semi-transparent white P.U. hose for dust-related pollutants.
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.

Alexander, Arkansas Fume Extraction Arm Mounting and Supports

Alexander, Arkansas Fume Extraction Arm Mounting and Supports

Fume extraction arms are continually moved, extended, and rotated, requiring them to be rigidly supported and mounted securely. A few factors affect mounting location: 1) the location of the fume source, 2) the coverage area for where the arm is used 3) the central system duct where the fume arm is connected.

Mounting options include:

Wall Mount - With duct systems running against a wall, mounting the arm (s) with brackets secured to a block wall or column is typical. If the central system duct is along the ceiling, on an outside wall, or mid-wall, there are designed brackets to fix the arm in place.

Bench Mount - Exhaust duct running along the floor allows mounting to a bench or tabletop. This mount has a standard option bracket for attaching the arm. Another standard bench mount is on a portable air filter or dust collector.

Ceiling Mount - Mounting the arms in the ceiling is an option if joists are present. A support weldment could be fabricated if a ceiling mount is a requirement. For low-weight short arms, the installation contractor can fabricate a wood fixture.

Stanchion Mount - When arms are located in the center of a facility having high bay areas, a stanchion will allow the mounting of an arm and hold it rigidly in place.

Economical Industrial Extraction Arms in Alexander AR


These extraction arms serve a similar function as the general-purpose extraction arm but are constructed with a flexible hose instead of metal tubing. This arm has cost savings, but some optional features are unavailable. These arms were designed for light-duty, intermittent applications and have limitations on some airstream constituents. Importantly, each application is reviewed upfront by SysTech will guide you through the selection process safely. Hose diameter alternatives range from four to eight inches, and arm lengths range from five to thirty-six feet. The standard hose material is blue PVC or white PVC with an option for PE-coated polyamide fabric for mild corrosive applications. Custom sizes can be designed using various parts for different arm models combined to make a new arm design.

Features and options:

  • External arm support
  • Lightweight construction balanced by two gas springs.
  • Unique ease of maneuverability
  • High positional stability
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
  • Arm diameters include 4", 5", 6", and 8", and arm lengths include 5', 7', 10', 13', 16', 23', 30', and 36'.
  • Hood designed for maximum capture efficiency and extraction
  • Lowest possible pressure drop, which helps save energy and lowers sound levels
Alexander, Arkansas Stainless Steel Extraction Arms

Alexander, Arkansas Stainless Steel Extraction Arms

Aggressive airstream chemistry may require the arms to be constructed of 304 stainless steel. The tubing and hood are stainless, with external adjustment joints at the hood and swivel joints. Arm assemblies have a wall mounting bracket and an internal damper for airflow adjustment and shutoff. The standard flex hose at the joints is an FDA Pur Antistatic hose. Stainless steel arm tube diameters vary from three to eight inches, and arm lengths from three feet up to fourteen feet, all suitable for washdown applications. 316 stainless steel construction is an available option.

  • Tubes, hood, internal shutoff damper, and duct connection collar are all constructed of 304SS
  • Clear anti-static FDA hose rated for 200 degrees Fahrenheit.
  • External joints are anodized aluminum.
  • Arm diameters include 3", 4", 5", 6", and 8", and arm lengths include 3', 5', 7', 8', 10', and 14'.
  • Available in hanging and benchtop models.
  • 304 SS grab handle on the hood for easy mobility and positioning.
  • Optional fume exhaust fans in aluminum, carbon steel, or PVC.
Alexander, Arkansas Fume Extraction Arm Optional Accessories

Alexander, Arkansas Fume Extraction Arm Optional Accessories

Fume extraction arms have optional accessories that include:

Hood lights – Lights can be attached to the arm hood to provide better vision at the work point. Often used in welding applications.

Floor Stanchion - When the ceiling is too high, or there are no walls, a floor stanchion can be used to mount the arm.

Ceiling Mount - For applications where arms are mounted/supported by the ceiling. The ceiling bracket varies in height depending on the height of the hard deck or Unistrut.

Wall Mount - A wall bracket designed to mount the arm to any wall or beam within the facility.

Nozzles - To get even closer to source capture, suction nozzles and flexible suction nozzles are available.

Tube materials – For those arms using tubing, construction materials include painted steel, aluminum, stainless steel, P.P., or PVC. Extraction arms that use flex hoses can use clear, fire retardant, high temperature, or anti-static hoses.

Custom hoods – To maximize fume capture, standard circular or scoop-shaped hoods can be changed to a slotted design, rectangular, flat, or custom fabricated.
